7 / 10 page 7/10 AN579 APPLICATION NOTE Figure 12. Fuse blowing function These components provide an absolute security after action, but their major disadvantage is the need for maintenance. Figure 13. PTC based protection The PTC thermistor is a device which operates by very rapid resistance increase as a function of the tem- perature. When the surge occurs across the line, the parallel protection PP is activated. The surge current Is, generated by PP action, flows through the PTC device and increases its internal tem- perature. As shown in Figure 14 the resistance value of the PTC device rises quickly with the temperature. .01 .1 1 10 100 t (s) I (A) 10 2.5A 1 100 LINE EXCHANGE PTC PTC Is PP PP |
